tinrrnn To all whom tmay concern: t y y Be it known ,that l, GUavARA J. Lnn, a. citizen of the United States, residing at Gori man, Maryland, have invented certain new and useful Improvements in Resilient Wheels, of which the following is a specifiinafter described andy particularly pointed out in the claim, it being understood that l do not wish to limit myself to the details of the different parts of my invention.

The invention is illustrated in the accompanying drawings, in which Figure l is a portion of a side elevation of a resilient vehicle wheel embodying' .in f invention, with parts in section. Fig, 2 is transverse view of one of the telly sections. Fin. 3 is a plan view of a portion of the wheel. Fig. e' is a longitudinal section of one of the tread links or sections. Fig. 5 is a view of a modified form oit tread\section, and Fig. 6 is a. raginental plan view of the telescopic connection between two of the sections or" the retracting hand. Fig. 7 is a perspective view of a modied forro of linlr.

In the drawings the ordinal l indicates the huh of the wheel, 2 the spokes, and 3 a sectional rim supported ley the spokes. -This rim is made up of telly sections 4i. l prefer to have the telly divided into sections or der ordinary circumstances. These sections are substantially U-shaped in cross section, as shown in Fig. 2. The rinror tread of the Wheel is made up of sections` 5, pivot'ed or hinged to each other as at 6. The tread sections are equal in ninn'ber to the telly .sections 4, and the pivots of the rim sections are in line .with the adjacent edges of the elly sections. The tread sections are, of course, of arc shape, as shown in Fig. et, and. are provided at one end with a tongue and at the other with a groove'S. `Wh1le in Figs. 3 and 4 the tread members are shown inode in one piece, I may inake these. of laminations or form a plurality of stamped out strips 5', which modification is shown in 'Ginvinnajnnn on ,soniianiianvnsnn l Specification of Letters Patent.

Fig. The tongues 7 lit neatly-into the grooves S when the sections arein placeV on`v` the wheel; they present an unbroken periphery and the sections are pivoted together by 'the pins 9. Sockets l0 are provided on the under side of the tread sections for a purpose hereinafter setfi'orth. Y

The tread sections 5 are spring sugmaorted,`

unattached except toeach other, in the U of the .telly sections 4 by means of 'pins l1 having hall or rounded heads lla, screwed thereon, adapted to lit into the sockets 10 of the tread sections. llhese pins are supported from the sectional rirn 3 hy helical springs l2 surrounding them.

The inner ends of theipins il are headed at i3, which are slidably held in thimbles 14, threaded into the sectional rim 3. Stops l5 are in the outer end' or the thimbles to act as liniits to the outward movement of the pins il, and plugs or dust capsid are in the inner end thereof.

The stops 16 are threaded into the thimhles so that they may he removed in case it `iould become. necessary to withdraw the il, in which event, however, it would iirst he necessary to unscrew therefrom the lball heads lla. .The thirnhles are further held rigid in the section al rim 3 by means of lock nuts i7. y

'ln operation the tread sections normally project half their thickness from the felly sect-ions. lt is obvious how an obstruction or nnevenness of road would, compress the tread sections into the U of the :telly sections by means of the springs 12', and the pins 11 sliding in the thinihles le. There are no stops to limit the inward movement of the tread sections, as when they are com-- pressed into the telly sections to be level with the legs thereof, it can he seen how they will he compressed no farther thereinto because' the periphery' of the tread sections and the telly sections will intersect at theV point or" hearing of 'the wheel upon the ground.

The wheel mayjbe provided with anti-` los' silient material, such-'as' rubber instead of sleeves, said pins hziving heads resting'. in Having the section'made entirely of metal. the sockets, and spnngs coiled around the I 'claim siny invention: pins and engaging the heads and sleeves. ,i In 'Ta plurality of spokes, a hollow In testimony ,whereof I aflixmy signature 5' fellybm ,lip Of'sictions correspoiding ii in presence'of two Witnesses.
